基于OOS-TEN的三维数据模型构建方法研究

Study on Construction of Three- Dimensional Cadastral Data Model Based on E- TEN

分析了现有的三维数据模型——实体模型、不规则四面体模型,在此基础上研究了三维实体的对象化过程,并提出了一种基于面向对象的实体-不规则四面体格网(OOSolid-Tetrahedral Network,简称OOS-TEN)的三维数据模型构建方法,对三维空间数据信息进行有效的组织,并建立基于Oracle Spatial的三维数据信息数据库,从而对三维数据信息进行有效的组织和管理。

This paper analyzes the existing 3D data model, entity model, irregular tetrahedron model, based on this research the ob- jectization process of 3D solid, and irregular was proposed based on object oriented entities - all physical Network （OOSolid -Tetra- hedral Network, hereinafter referred to as OOS - TEN） of the 3 d data model building method, the three -dimensional data informa- tion effectively, and establish the based on 3D data of Oracle Spatial information database, and thus to the 3D data information for ef- fective organization and management.
